RFR: 8364185: [BACKOUT] AArch64: [VectorAPI] sve vector math operations are not supported after JDK-8353217

[Jaikiran Pai]

Can I please get a review of this change which backs out the changes done in https://bugs.openjdk.org/browse/JDK-8363063? The linux-aarch64 builds in our CI started failing after the changes in JDK-8363063 were integrated. 

The description in the backout issue https://bugs.openjdk.org/browse/JDK-8364185 has the details about the build failure errors.

The commit in this PR backs out the change (`git revert 011de4c894ed827ee8e15a7cfe400788175e5b2c`). CI jobs are currently in progress to verify that this backout fixes the build failures.

A new REDO issue has been created https://bugs.openjdk.org/browse/JDK-8364184 to redo the original change and address these linux-aarch64 build issues.
